Test Line Cards and Network Equipment with Stressed Live Traffic

The BERTScope Stressed Live Data Software Option enables engineers to add various types of stress to real data traffic in order to stress devices with bit sequences representative of the environment they will encounter once deployed. Using live traffic with added stress tests the boundaries of device performance and lends added confidence to designs before they are shipped.

Unstressed live traffic from a line card can be stressed by the BERTScope up to the full data rate of the BERTScope. Use the BERTScope CR to provide a recovered clock.  The BERTScope requires a full rate clock up to 11.2 Gb/s, or a half rate clock above 11.2 Gb/s.

Historically, system level manufacturers and service providers have not been able to perform testing with a receiver jitter tolerance signal, or “stressed eye”. Instead, they have had to rely on component level testing that the individual transceiver devices are put through without the effects of line card interconnects and other potential sources of lurking problems.

With Stressed Live Data on the BERTScope, line cards and network equipment can be tested with stressed live traffic, the only way to know for sure that there aren’t problems arising at network interfaces.

Setup is easy. Just set the Generator to output data that has been "passed through" from the Detector (top), and add the user-settable stress (bottom).

BERTScope Makes Stressing Live Data Easy

Adding stress to live traffic is easy with the BERTScope. The intuitive user interface makes setup fast and easy and all the flexibility of the BERTScope stress generation are at your fingertips.

The data is re-timed inside the BERTScope, and the stress is added to a clean signal. This allows users to rely on the calibrated stresses that come with the BERTScope instead of having to guess how much additional jitter to inject on top of the jitter already present.

Key Capabilities

• Full range of stress available on the BERTScope, including Sinusoidal Jitter (SJ), Random Jitter (RJ), Bounded Uncorrelated Jitter (BUJ), Sinusoidal Interference (SI), F/2 Jitter, and Spread Spectrum Clocking (SSC)
• Data rate support up to the maximum of the BERTScope
